8 Claims.

This invention relates to improvements in shingles and method of manufacturing the same, and is a continuation in part of application Serial No. 220,302 filed September 19, 1927.

Heretofore, separate metal clips have been affixed to strip roofing in spaced apart relation to form means for engaging the lower edge of a strip above so as to lock said edge in position. Separate clips are troublesome to apply, and

1 when it is desired to have the clips engage the strip above at predetermined points, it is difficult to apply the separate clips in properly spaced relation during the process of manufacture of the roofing. As a result of this difficulty the clips had to be applied by the roofer, as the strips were being laid, in order to insure proper positioning of said clips. This necessarily increased the time required to apply the roofing and added to the expense connected therewith.

It is, therefore, one of the objects of this invention to overcome the above mentioned objectionable features by providing improved shingles and method of manufacturing the same, in which securing means is applied to the shingles by means of continuous bands which are provided with the securing means thereon in properly spaced relation. These continuous bands may be applied to the traveling web during the process of manufacture and they may be posi- 80 tioned and guided in place in exact relation to the speed at which the web travels so that the securing members will be properly positioned with relation to the shingle elements.

A further object of this invention is to provide improved shingles which are simple in construction, simple to apply to a roof, relatively inexpensive to manufacture, and well adapted for the purpose described.

With the above and other objects in view, the invention consists of the improved shingles and method of manufacturing the .same, and all its parts and combinations, as set forth in the claims, and all equivalents thereof.

In the accompanying drawing, illustrating one complete embodiment of the preferred form of the invention, in which the same reference numerals indicate the same parts in all of the views:

, Fig. 1 is a plan view of a section ofroofing web, showing the method of forming the improved shingles and the method of applying the bands carrying the locking members;

Fig. 2 is a pian view of one of the shingle strips;

Fig. 3 is a plan view of an assembly of two shingle strips;

Fig. 4 is an enlarged fragmentary sectional view of said assembly; and

Fig. 5 is an'enlarged plan view of a portion of a band carrying the locking clips.

Referring to the drawing, it will be seen that the improved shingle comprises a strip of material 33 having a serrated lower edge 34 to simulate a plurality of units on a single strip. Said body portion has the units thereon colored in three different manners as at 35, 36, and 37 so that when the strips are laid on a roof in rows as shown in Fig. 3, the colors on the various strips alternate, the arrangement being such that no two, similar body portions are in contact.

Obviously, any of the shingles illustrated herein could be laid in horizontalrows as well as in inclined rows.

The means which is provided for locking the exposed portions of the shingles down on the roof comprises a continuous band 40 which is fixed, in any suitable manner, to the upper side of the shingles or strips adjacent the upper edge. These bands are preferably fixed to the shingles so as the latter are being manufactured, as will hereinafter be described, and they may be cemented, riveted, or secured to the sheet by means of asphalt or silicate of soda. The bands are preferably formed of metal, but paper, cloth, or 35 any other suitable material may be employed.

Lugs or clips 41 are fixed to the bands. These clips are formed preferably by cutting slits 42 in the bands and by bending the clip 41 out of the plane of the band. When the shingles are laid, the corners 43 are slipped under the clips 41, the position of the bands on the shingles being such that these lugs will be in the proper position to receive the edges of the overlying shingles when the latter are properly positioned on the roof. Thus the locking bands form convenient means for guiding the shingles into position.

These bands also form convenient means for assisting in nailing the shingles to the roof, as

nails may be readily positioned by the indicating means or apertures 44 and may be driven through the strips as well as the shingles, thus providing a much firmer means for holding the shingles 'down on the roof and preventing any tendency of the shingles being pulled from the nails.

In the preferred manner of manufacturing the shingles, the bands 40, which have been previously formed with the clips 41 thereon in a predetermined spaced apart relation, are applied to the roofing'web in the manner shown in Fig. 1, 110

as the latter is travelling, and the bands will be positioned and. guided in place in exact relation to the speed at which the web travels. The travelling web is also passed beneath a cutting roll which severs the web on the zig-zag line 45 to form two shingle strips having serrated edges. The clips 41 must be spaced apart on the band the same distance as the distance between two projecting points on the shingle strip, and it is merely necessary to start the application of the band so that one clip is in alinement with one projecting point on the strip. The remaining clips, due to the use of the continuous band, will then necessarily be properly positioned. This method of applying continuous bands to the travelling web makes it possible to accurately position the clips in a minimum of time.

While the above is the preferred method, the band may be rolled up with the finished product and applied by the roofer when a roof is being laid.

Although the locking band has been shown as used in connection with a shingle strip having a serrated edge, it may be used as eificiently on any type of roll roofing, and the exact construction of the band may be varied, it being understood that this invention includes all adaptations, changes, and modifications as may come within the scope of the claims.

What I claim is:

1. The method of forming strip shingles comprising severing a traveling web along a line extending longitudinally of the web to form shingle strips having edges provided with tabs and recesses, applying to a face of said web while the latter is in travel, a continuous band presenting locking members spaced apart thereon at positions corresponding to the spacing of the tabs on the shingle strips to position all of the locking members at definite points with relation to all of the tabs and recesses.

2. The method of manufacturing shingles comprising forming on a traveling web an elongated strip to simulate a plurality of figures, arranging on the strip a band presenting a plurality of locking means spaced apart distances corresponding to the spacing of the figures on the strip, positioning one of the locking means in proper relation to one of the figures of the strip and mounting said band while the latter is in motion to thereby accurately position all of the locking members with relation to all of the figures on the strip.

' with locking means, the steps of providing a moving strip of composition material; during manufacture and while said strip is in motion positioning upon the face to be exposed when laid, a continuous strengthening band presenting aplurality of hook-like locking means, locating said band substantially parallel to an edge and adjacent an edge of the strip which is to be covered when the material is laid to space the locking means in a definite relation to said parallel edge, and winding said strip into rolls after the band has been applied, said band serving to maintain the relation of said locking means with the edge of the strip and said locking means being adapted to hook around and lock down the weather edge of an adjacent overlying strip in assembly without penetrating said edge. 1

5. A shingle element comprising an elongated strip of flexible shingle material having a lower weather edge and overlying lines of demarcation upon its face to be exposed to the weather defining in part a plurality of individual figures; an afiixed, continuous strengthening band upon said face to be exposed, spaced from an edge opposite the lower weather edge a distance equal to the desired lap when laid and substantially parallel to the lower weather edge; a plurality of hooklike, non-penetrating positioning and locking means on said continuous band, spaced apart in predetermined position corresponding to the spacing of the partially defined figures and equally distant from the lower edge of the strip; said band serving to maintain a definite relation of the looking means, figures and lower weather edge prior to assembly and said locking means being of a size and form to hook around the lower weather edge of an adjacent overlying element in assembly to quickly position and lock down said edge with the desired lap and to complete a row of defined figures.

6. A shingle element comprising a body portion having an edge defined by depending tabs and recesses, an afiixed strengthening band upon its face to be exposed to the weather and adjacent an edge to be covered by an overlying shingle element in assembly, a plurality of locking hooks on said band adapted to hook around the lower edge of an overlying element at the recesses and spaced apart distances corresponding substantially to the spacing of the tabs and at definite points with relation to all the tabs and recesses, said band 115 being adapted to maintain the relation of locking hooks, tabs and recesses prior to assembly and said hooks being adapted to quickly and properly position the tab defined edge of an adjacent overlying element to complete a row of shingle figures 120 and to lock down said edge with a desired lap.

7. As an article of manufacture, a shingle strip comprising a body portion having an edge formed with alternating tabs and recesses, a continuous band aflixed to the body portion and presenting 125 nail positioning indicators located in a definite relation to the tabs and recesses to give maximum weather protection to the nails when the shingle strips are assembled, hook like locking means on said band spaced apart distances corresponding 130 substantially to the spacing of the tabs and at predetermined points with relation to all the tabs and recesses and of a size and form to receive, hook around and lock down the edge portions of recesses of an overlying strip in assembly.

8. A roof covering comprising courses of overlapping shingle strips laid without exposure of the building foundation beneath and simulating a plurality of individual shingle elements; each strip comprising a body portion having an edge 140 defined by alternating tabs and recesses, a continuous nail receiving and strengthening band prefixed on the front face of said body portion spaced from an edge thereof a distance equal to the desired lap when laid, a plurality of hook like 145 locking means on said band spaced apart distances corresponding substantially to the spacing of the tabs and at predetermined points with relation to all the tabs and recesses and of a size and form to receive, hook around and lock down 150 tab-formed edge locked down by the hook-like locking means of a lower strip, and said band providing a firm means for holding the shingle strip to the foundation and preventing the shingle,

pulling away from its nail securing means.
